CLAMP.

Specification of Letters Pedcentv Fatented Feb 8, 19241.

Application filed October 24;, 1919. Serial No. 332,982.

. lowing is a specication.

This invention relates to improvements in clamps for holding lids of churns, jars and the like in place.

it provides a clamp for this use which is simple in construction, inexpensive to manufacture and. fits practically all sizes of jars without any material adjustment.

In addition to the foregoing, objects of the invention are to provide a clamp with lid holding members, engaging the lid at several points, and at both the periphery and top or the lid, so as to prevent sidewise and upward displacement of the lid while, for instance, the dasher of a churn is being operated.

With reference to the drawings:

Figure 1 is a perspective of a jar clamp constructed in accordance with my invention.

Fig. 2 is a side elevation of a jar hav ing the clamp shown in Fig. ,1 applied thereto.

ig. 8 is a perspective of a modified form of clamp, and

Fig. 4: is a side elevation of a jar having the clamp shown in Fig. 3 applied t iereto.

In detail:

The invention as shown in Figs. 1 and 2,

is applied to the jar body A and consists of a substantially circular spring wire 1 tensioned so as to spring around the jar body and be seated against upward movement by engagement with a rib, flange, groove or like means, found on every jar adjacent the opening thereof.

The spring wire 1 has the ends 2 and 3 turned upwardly then inwardly and downwardly as shown at 6 and 7 respectively, to form lid holding members: equidistant from the ends 2 and 3, a third holding me1nber 4t is formed bylooping the wire so that the loop extends upwardly and then bending the end of the loop down as shown at 9.

Equipped as thus formed is a single element made from a length of wire and engages the lid at the sides and top at three equidistant pointswhich serves the double function of holding the lid from sidewise practice screw thr ing said circular spring wire, to vary so as movement and also from upward displacement.

in the modification shown in Figs. 3 and a a clamp is also termed from a single length of wire 11 bent and tensioned circumferentially. However, the wire in this instance carries three upward loops 12, 13and 14 each twisted as shown at 15 and bent down-' wardly as at 16, 17 and 18, respectively, so that these l10ll111I members also engage the lid 10 at the periphery and on the to at three equidistant points. The ends of the wire 11 extend, respectively, through dif- :terenportions of a clip block 19, one end being bent down as shown at 20 and the other end bent up as shown 21, as illustrated in Fig. l. The set screw 22 is threaded into the clip block screwed in, to engage the wire 11. The advantage of this construction is that the clamp may be tightl adjusted and locked in place around the jar body A by simply loosening the set screw 22 pulling on the 19 and adapted, when end 21 and then, while the wire 21 is being pulled on the set screw is screwed into engagement with the wire 11.

The jar and clamp hereinbetor'e described is of simple construction and may be used with practically all churns, stone crocks, jars and the like and the lid of such receptacles when the clamp is used cannot be, accidentally displaced.

While I have herein described specific embodiments of my invention it is nevertheless to be understood that, do not con fine myself to such specific devices but may the invention to the full scope of the terms of the claim.

Having thus described my invention what I claim as new is up tightly A cover for jars comprising a substangers turned upwardlythen inwardly and downwardly to form lid holding members,

said fingers being formed with twists, a

block having holes through which said circular spring wire passes in opposite directions and being laterally bent soas to prevent dise oagementfrom said block, a set .ded into said block for adjustto fit a jar of any desired size.

In testimony whereof I affix my signature,
